Rectorseal Metacaulk 7" x 7" Fire Rated Putty Pad

The Rectorseal Metacaulk 7" x 7" Fire Rated Putty Pad is a one-component, fireproof putty pad designed for electrical boxes, conduit, and other through-penetration firestop systems. This moldable, non-curing pad expands (intumesces) when exposed to heat, forming an insulating char that blocks flames, smoke, gas, and water.

Tested for fire resistance up to 3 hours and with a Sound Transmission Class (STC) rating of 60, these fire putty pads deliver reliable performance while keeping assemblies code-compliant. They install easily by hand with no tools or mixing required.

Key Features

  • Size: 7" x 7", 1/8" thick
  • Fire Rating: Rated up to 3 hours (ASTM E 814, UL 1479, ULC/CAN4-S115-M)
  • Sound Rating: STC 60 with only one pad needed for 1–2 hour ratings
  • Best For: Firestopping electrical boxes, conduit, and junction boxes
  • Material: Moldable, non-curing putty that intumesces under heat
  • Code Compliance: Required in rated partitions when box separation is under 24"
  • Durability: Resists moisture, vibration, and extreme temperatures
  • Safety: Contains no volatile solvents and no asbestos fillers

Applications

  • Sealing metallic and nonmetallic electrical boxes
  • Large and small junction boxes
  • EMT pipe, conduit, and bundled cabling (telephone, power, communications)
  • UL-approved use with Metacaulk FRM Mortar designs for added protection
  • Provides a barrier even under vibration and movement
